Weizhi:

1) Comparison between Bosted and MAID (g2p) inelastic algorithm
- some electrons below pion production for MAID algorithm (need to be removed)
- larger peak for MAID, second resonance larger for Bosted (as in Nick's code), small shift of the peak also
- comparison with data:
  - large PWO angle: data larger than both simulation at first peak
  - LG angle range: simulation larger at first peak, between simulations at second peak
- separating PWO and LG: second peak badly matching for PWO
- 1GeV data: width of peak not matching at larger angle
- LG region more sensitive to energy cut
- shifting second peak in simulation for better match raises super ration of 1%

2) Non linearity correction
- <1% shift for lower angle (for Moller energy)
- becomes larger when going to larger angle (smaller energy)
- normally  no effects on inelastic peak

3) Comparison of reconstruction algorithm (5x5, primex island, new island)
- very close in position reconstruction
- yield change <1% ( a bit more for 5x5 probably due to calibration)
- largest difference in energy spectrum in transition region
